emulation testbeds,
computing clusters that offer virtual machines on servers that are interconnected by a high speed switch, enabling large scale network emulation.

This list of types of platforms is subject to change, and the current list, along with the identities of the specific platforms of each type, can be found
on the OneLab website (onelab.eu).

Each platform has its own owners, and OneLab is the grouping of these platforms through a consortium of institutions. The OneLab consortium is coordinated
by UPMC Sorbonne Universités. It operates on a not-for-profit basis.

Access to OneLab may also provide access to additional platforms that are not part of OneLab, due to a federation agreement between OneLab and the owners
of those platforms.

1.2 Fee-free Basic level service

These terms and conditions define and apply to OneLab's Basic level service, which is available free of charge.

Users who would like additional services are encouraged to contact support@onelab.eu. Some additional services require a written agreement, but are
otherwise free. Others require the payment of fees or in-kind contributions. (An example of an in-kind contribution is the hosting of a PlanetLab Europe
server node.)

1.3 Managers and standard users

There are two classes of OneLab user: the manager and the standard user. OneLab grants access rights to managers, who, in turn, provide access rights to
standard users. Examples are: for a small enterprise, an executive may be the manager and the employees may be standard users; for a research team, a
senior scientist (faculty member or research scientist) may be a manager and doctoral students and other members of the team may be standard users; for a
university course, a professor may be a manager and the students may be standard users.

1.4 These terms and conditions

Acceptance of these terms and conditions is a condition of obtaining OneLab Basic level user service. They are posted to the OneLab portal site
(portal.onelab.eu). They may be changed without other notice than the posting of a new version to the portal site.

2 Services provided by OneLab

2.1 Access to the experimental facility

OneLab provides users with access to the platforms that make up the experimental facility. Each platform owner determines the specifics of this access (for
example, how many nodes are available to a user, what happens in case of oversubscription, etc.), with the proviso that Basic level service requires that
users be able to conduct meaningful experiments on every OneLab testbed.

Basic level service may also provide access to platforms that are federated with OneLab, but such access depends upon the terms of the federation
agreements with those platforms, which may require that the user have a higher level of service in order to gain access. For example, Basic level service
provides access to PlanetLab Europe, a OneLab platform, without providing access to PlanetLab Central, a federated platform. Users wanting full access
across the global PlanetLab system should contact support@onelab.eu to arrange to enter into a PlanetLab Europe membership agreement.

OneLab's role is to facilitate access to the platforms. Specifically, it provides each user with:

a single account,
the credentials for which can be used to access all of the OneLab testbeds;

tools through which to access the testbeds
, including, notably, a web-based portal (portal.onelab.eu) that allows a user to see the resources available on each testbed and to reserve them,
along with a number of experiment control tools that a user can employ to deploy an experiment on those resources;

support
, with documentation on how to use the tools, pointers to documentation for individual testbeds, and a helpdesk to respond to user questions.

Additional support, such as accompaniment through the design and deployment of experiments and the interpretation of their results, is available through
higher levels of service.

2.2 Best effort, without guarantees

OneLab and the owners of the individual OneLab testbeds do their best to provide the services outlined here, with the understanding that Basic level
service offers no guarantees. Users should clearly understand the following limitations.

Reliability:
OneLab does not provide any guarantees with respect to the reliability of the portal, of other tools, or of the individual nodes on platforms. These
may be taken down for maintenance, rebooted, or reinstalled at any time. Reinstallation implies that disks are wiped, meaning that users should not
consider a local disk to be a persistent form of storage.

Fitness:
OneLab does not guarantee that the platforms are suitable for the experiments that users intend to conduct. There may be limitations in the
technologies that are offered that prevent certain types of experiments from being carried out.

Privacy
: OneLab does not guarantee the privacy of traffic generated on the platforms (e.g., wireless signals, packets). Unless otherwise specified by an
individual platform owner, users should assume that traffic is monitored and logged. Such monitoring may be done intentionally, for example, to allow
platform administrators as well as other users to investigate abuse.

Users who seek such guarantees are invited to consider a higher level of service.

2.3 Limitedliability

In no event shall the partners of the OneLab consortium be liable to any user for any consequential, incidental, punitive, or lost profit damages, or for
any damages arising out of loss of use or loss of data, to the extent that such damages arise out of the activities of OneLab consortium partners, or any
breach of the present terms and conditions, even if the consortium partner has been advised of the possibility of such damages.

Nothing contained in these terms and conditions shall be deemed as creating any rights or liabilities in or for third parties who are not Basic level users
of OneLab.

3 Acceptable use policy

3.1 Responsibilities of managers and standard users

OneLab creates and administers accounts for managers and delegates to managers the responsibility for creating and administering accounts for standard
users. Both managers and standard users are required to follow OneLab's acceptable use policy. In addition, managers are fully responsible for the
activities of the standard users whose accounts they create.

A manager is expected to grant user access only an individual with whom he or she has a working relationship. In general, this means an individual who
works for the same institution as the manager, or, in the case of higher education and research, an individual who is a student at the university where the
manager works. Managers may also grant access to individuals from other institutions, provided that they are collaborating on a common project on OneLab.
If there is a doubt, a manager should refer the question to support@onelab.eu.

3.2 Types of use

OneLab may be used by enterprise, by scientific researchers, and by educators.

OneLab may be used for pre-commercial research and development. In keeping with OneLab's not-for-profit status, it may not be used to deploy services that
are designed to generate a commercial profit.

Not-for-profit use of OneLab to deploy services that are designed to generate revenue requires prior approval through a written agreement, and thus may not
be carried out on a Basic level account. Interested users are invited to contact support@onelab.eu.

OneLab may be used for scientific research.

OneLab may be used to host lab exercises for university courses.

Questions about other types of use should be addressed to support@onelab.eu.

3.3 Applicable laws and regulations

OneLab is managed, and the portal is hosted, in France. Information regarding the countries in which individual testbeds are managed and hosted is
available from those testbeds. Users are responsible for being aware of the countries in which their experiments are deployed and for ensuring that their
use of OneLab fully conforms to the laws and regulations of those countries, as well as the laws and regulations of the country in which they themselves
are present when conducting their experiments.

Above and beyond specific national laws, the activities email spamming, phishing through web services, and all types of Internet fraud are prohibited on
OneLab.

3.4 Security and accounting mechanisms

Users are expected to respect the security and accounting mechanisms put in place by OneLab, its platforms, and federated platforms. For example, access to
PlanetLab Europe is designed to take place through the SSH cryptographically-secured connection protocol, which uses public/private key pair
authentication, and so users should not attempt to bypass this mechanism. As another example, OneLab's notion of a "slice" associates a set of resources
with the group of users who have reserved those resources, and users should not attempt to obscure the identities of participants in a slice.

Hacking attempts against the OneLab portal and testbeds are not permitted. This includes "red team" (hacker test) experiments.

3.5 Sharing of resources

OneLab is intended for ambitious experiments. Large numbers of resources and extended leases on resources may legitimately be granted in order to carry
these out. At the same time, OneLab and its testbeds are shared environments, and when there is contention for resources, limits must be imposed.

Each OneLab platform sets its own policies for handling resource contention. As a general rule, users are encouraged to design their experiments to use
resources efficiently. In particular, spinning/busy-waiting techniques for extended periods of time are strongly discouraged. Some resource contention
policies (e.g., PlanetLab Europe's) terminate the jobs that are using the most resources in the case of contention.

3.6 Internet-connected platforms

Some of OneLab's platforms allow experiments to take place on resources that have access to the public internet. These experiments can potentially generate
traffic to, and receive traffic from, any host or router in the internet.[LB1]

Furthermore, some internet-connected platforms (e.g., PlanetLab Europe) consist of servers that are hosted by a large number of member institutions.

The accessibility of internet-connected platforms and the distributed hosting model of some of these platforms imply certain responsibilities on the part
of users, as detailed below.

3.6.1 General guidance

A good litmus test when considering whether an experiment is appropriate for such internet-connected platforms is to ask what the network administrator at
one's own organisation would say about the experiment running locally. If the experiment disrupts local activity (e.g., uses more than its share of the
site's internet bandwidth) or triggers complaints from remote network administrators (e.g., performs systematic port scans), then it is not appropriate for
such internet-connected platforms.

It is the responsibility of the user and the user's manager to ensure that an application that will run on an internet-connected platform is tested and
debugged in a controlled environment, to better understand its behaviour prior to deployment.

3.6.2 Standards of network etiquette

Internet-connected platforms are designed to support experiments that generate unusual traffic, such as network measurements. However, it is expected that
all users adhere to widely accepted standards of network etiquette in an effort to minimise complaints from network administrators. Activities that have
been interpreted as worm and denial-of-service attacks in the past (and should be avoided) include sending SYN packets to port 80 on random machines,
probing random IP addresses, repeatedly pinging routers, overloading bottleneck links with measurement traffic, and probing a single target machine from
many nodes.

For internet-connected platforms that have a distributed hosting model, each host institution will have its own acceptable use policy. Users should not
knowingly violate such local policies. Conflicts between local policies and OneLab's stated goal of supporting research into wide-area networks should be
brought to the attention of OneLab administrators at support@onelab.eu.

3.6.3 Specific network usage rules

It is not allowed to use one or more nodes of an internet-connected platform to generate a high number of network flows or flood a site with high traffic
to the point of interfering with its normal operation. Use of congestion-controlled flows for large transfers is highly encouraged.

It is not allowed to perform systematic or random port or address block scans from an internet-connected platform.

For internet-connected platforms that use a distributed hosting model, it is not allowed to spoof or sniff traffic on a hosted server or on the network the
server belongs to.

Access to a server on a distributed hosting platform may not be used to gain access to other servers or networked equipment that are not part of the
testbed.

3.7 Wireless platforms

Wireless-connected platforms give users access to nodes that communicate via Wi-Fi and other wireless technologies. They may be capable of detecting
wireless activity in the neighbourhood of those nodes: traffic generated by other users of the platform or by individuals not associated with the platform.
In general, much of the traffic will be encrypted, with certain aspects (such as SSIDs) not encrypted, but it is also possible that there will be fully
unencrypted traffic. They may also be capable of generating wireless activity that reaches equipment outside of the testbed.

Furthermore, some wireless-connected platforms may have built-in limitations to prevent them from generating signals at a strength that exceeds health and
safety regulations.

These characteristics of wireless-connected platforms imply certain responsibilities on the part of users, as detailed below.

3.7.1 Specific network usage rules

Experimenters may make no attempt to defeat the encryption of encrypted third-party traffic. Furthermore, experimenters must treat with utmost discretion
any unencrypted traffic. Limited metadata can be recorded for the bona fide purposes of an experiment, but under no case should third party communications
be recorded.

No attempt may be made to reverse engineer traffic in order to learn the identities of the parties who have generated the traffic.

Wireless-connected platforms may not be used to gain access to any network equipment that is not part of the testbed itself.

It is not allowed to perform systematic or random scans of wireless networks that are not part of a wireless-connected platform. Similarly, it is not
allowed to spoof or sniff wireless traffic of the institution that hosts a wireless-connected platform or of other networks in the proximity.

Care must be taken so that traffic on wireless-connected platforms does not interfere with the normal functioning of network equipment that is not part of
the testbed itself.

No attempt may be made to defeat the mechanisms that limit signal strength on wireless-connected platforms.

3.8 Handling suspected violations

Suspected violations of the OneLab acceptable use policy should be reported to support@onelab.eu.

Upon notification or detection of a possible violation, OneLab management will attempt to understand if a violation has in fact occurred. To do so,
management will freely communicate with the users concerned, the operators of the platforms concerned, as well as any third parties that might be involved.
An example of a third party is a network operator who detects what they believe to be unauthorized traffic emanating from a OneLab platform.

The priority is to resolve any real or apparent violations amicably. However, if OneLab management believes that a violation may have occurred, it can, at
its sole discretion, and without prior notice, apply any of the following measures:

notification of the users of the concerned slice (set of resources);

disabling of the concerned slice;

disabling an individual user's account;

reporting of the user's activity to his/her manager;

disabling of the manager's account and all user accounts for which the manager is responsible;

disabling of all accounts associated with the user's institution.

In the case of suspected illegal activity, OneLab management might need, without prior notice, to notify the relevant authorities.
